IMPROVEMENT IN HUBATTACHING DEVICES.

Specification forming part of Letters Patent No. 190,052, dated April 24, 1877,' application tiled February 21, 1877.

To all whom it may concern:

Be it known that we, JAMES LATHROP and FRANK H. ALLEN, both of the city of Norwich, county ot' New London, and State of Connecticut, have invented certain Improvements in the Method of Securing Vehicle- Wheels to Axles, of which the subjoined is a specitication Our especial lobject is to so construct an axle and wheel that the wheel may be instantly removed from or attached to the axle without detaching or unscrewing a nut or bolt.

In the accompanying drawing, designated as Figure l, A represents a carriageaxle, B, a hub; and (l, an intermediate tube, on which the hub B rotates. On one end ot' the tube O is a head or lange, b, Fig. 2, which, when the tube is in place, holds the hub B on the axle. On the other end of the tube U are provided lugs having' transverse slots, as shown at a, Fig. Z, by which the tube C is locked or made fast to the flange of the axle at c, Fig. l. This ange c, Fig. 2, has slots extending lengthwise or parallel with the axle A, through which the lugs a, Fig. 2, pass as the tube C is slipped onto the axle A. d, Fig. i, is a tlat spring, held in place by a screw at e, and operated by a headed rod or boltblank seated in a suitable opening in the axle, and beneath the spring d, so that when it is forced upward the spring d is thrown up, thereby releasing the tube C, which in turn releases the hub B.

This device is intended to be used in connection with the jack ordinarily used for raising the Wheel from the ground or door to lubricate or wash it.

To operate our device, place the jack under- 1 neath the rod f, which, as it receives the up- 'Ward pressure from the jack, will raise the spring d to a height sufficient to allenT the tube C to be removed, which is done by turning the wheel and tube backward until the lugs c, Fig. 2, are released from the ange c, Fig. l, when the wheel and tube may be withdrawn from the axle. The tube may thenbe removed from the hub and cleaned or repairedat pleasure.

The wear in this device cornes on the tube C, and not on the axle, as is usually the case, so that should the tubes become Worn andreduced in size new ones may be substituted at a trifling cost.

The tube U is provided with suitable holes, through which the oil or axle-grease may penetrate, and, after passing around the axle, (inside of the tube,) will again pass out ofthe holes in the bottom ot' the tube and be carried around by the hub as it rotates.

We claiml. In combination with the axle A, the tube C, provided with the iiange b, locking-lugs c, and openings fi, as described, and for the purpose specified.

2. In combination with the axle A :and tube O, the spring land rod f, all arranged and operated as and for the purpose specilied.

In witness whereofl we have hereunto set our hands and seals this 19th day of February, A. D. -187 7.
